i TANK-CAR.' f f To all 'whom t may concern: i

Be it known that I, LOUIS E. ALLYN, la citizen of the United States, residingV at. Pekin, in the county of Tazewelland State of Illinois', have'invent'ed certainA newand useful Improvements inV Tank-Cars,qof which the 4following is a specification.v f

My invention relates to tank cars, and particularly to means for anchoring the tank upon a car'underframe, and to means of conf nection therebetween to permit limitedlonfgitudinal movement thereof and to facilitate a ready detachment ofl the` tankjrom` the underframe.

:In the drawings, Figure 1 is a side elevaf tion showing a portion of a tank andan un-j' derframe with my device attached; Fig. 2 is a plan view of my device; Fig. 3 isa vertical sectional view Von the line 3`3,of Figi.; 2;'.

Fig. 4 lis a vertical sectional view t'hronglrI the line 4 4 of Fig. 2, and Fig. 5 isa detail view of afollower board. V 1 In the drawings, Aare parallel ,channel-l beams longitudinally `disposed with refer-1 ence to the ordinary car trucks andare adapter|to be suitably supportedupon said trucks and are `provided with afseries` of slots a. B is a tank and C is a'plate adapted to be' riveted to thebottom thereof, provided with shoulder portions D adapted to be seated upon channel-beams A, the saidplate being also provided with a portion E'a'daptedlto depend between the channel-bears yA, said depending portion being equipped withY strengthening ribs F, as best seen in Figs. 3 .and i and also provided with slots each of the walls thereof yadapted to.' carry lthe anchoring keys.

.The depending portion-E is adapted tol bei detachably intel-locked with vtheV channel-1 beams of the underframe by means of keys O andO passing through slots okey-Ways a in said channel-beams, said `slots or keyways being cut through the neutral axis 4of, said channel beams, that is, inthe part of the web of such beams whichwill be neutral, yor will be under neither tension --nor compression when'the beamhasv a tendency to bend, said slots being of considerably greater length than the width of the keys, said keys being hc-ld in' a substantially fixed relation with depending -portion E, thus adapting the tank to be moved l"backwardly i `Spleciiicetion,of Letteurs Patent.

For the purpose of limiting the movement of the tank upon the channel-beams, abutment blocks'G and -Gare provided which are supported between thechannel-be'ams by PatentedFeb. 8, 1916'.y Application led April 6, 191,0.

means of keys, the one indicated as L being designedto support24 block Gand the lone designated as L sup' ortin block G.

l H and H P g are Vabutment blocks bearingre- I spectlvely againsttheend walls of depende ing portion E,'said blocks being-supported, Y

by means o f key N and I have interposed coil springs M betweenfblocks G and I-I, supporting the same upon studs g and gf located respectively uponv blocks G and -H`, and g spring M between blocks G andy H and said springs 'M' are s supported fupon studs g? yand g3 respectively upon blocks H and G. The keys L andgL, and N and N are passed through the` slots a in the channel beams,-`there being corresponding slots inl bothA beams, and'said slots beingsubstantially about two-thirds the length which carry'the keys Ol and O. l

For the purpose of distributing the stresses onV the cushioning springs upon kthe springs attending the movement ofthe tank inv/either direction of its movement, I have provided "the follower boards K, whichk said boards are provided with slots as l l', whichv are of size -j ust suficient'to permit keysO O4 tobe passed therethrough. Thev connection of the follower boards with'the keys vO and O lwill cause said boards'to' be moved with the depending portion E. The normal relation ofthe keyswith reference tothe foll lower board is as disclosed inFig. 1, 1in" whichfigure keys Land L occupy positions at opposite outward extremities ofvfollower boardslots c, c and-keys N and N at the extreme limits of the slots z', vz" nearest depending portionEf The keys occupying the l v position relative to the slots in the follower board asindioated inFigs. 1, 2, and 4, then Whenthe tank is moved to the right, the depending ;portion E abutting with. block H will cause spring M to be compressed against p the ,stationary-block G and the slot lc in the follower board Will permit the boardto be moved to thel-imit ofthe slot, throughwhich said key is passed, andkey N will pass forwardly in I the direction of vmovement i of the tank resting in A sl`ot i', and during .such movement the follower boardwill cause key-L lto draw block G forwardly against` spring M, thereby dividing the strain. upon vsprings M and M. A` reverse movement of i supports the tank against lateral thrust and serves as an ,aid to shoulders D in preventing the tank from turning. The keys connecting the underframe tothe tank will render the latter readily detachable from the former and serves to prevent vertical jumping of the tank upon the frame, and also in conjunction with the bearing of the shoulders D upon the upper faces 'of the channelbeams, prevents longitudinal rocking` I I have shown one form of embodiment of my invention but other forms may be employed without departing from the spirit thereof. 4

Cutting the-key-ways for the keys through the neutral aXis of the sills is a decided advantage over cutting such key-ways in either that part of the sills subjected to stresses of tension or compression, as, in any other location than in the neutral axis, the key-ways will become a decided source of weakness to the structure comprising such sills.

What I claim is: v 1A. In a tank car, a pair of sills, a tank provided with a portion depending between the sills, a pair of movable stop blocks on each side of the depending portion, resilient members interposed between each pair of stop blocks, and vmeans forl connectingthe depending portion and the stop blocks 1n a .relation that a longitudinal movement of the tank in either direction will cause a corresponding compression of both the resilient members.

2. In a tank car, a pair of sills, provided with a plurality of longitudinal slots therein, a tank provided with a portion depending between the sills, a pair of stop blocks on each side of the depending portion, springs interposed between each pair of stopl blocks, follower boards .interposed between the sills and the depending portion and stop blocks, bars connecting the depending portion, the follower boa'rds and the sills 1nl a relation that the longitudinal movement of the depending portion will carry with it the follower boards, and bars connecting the @5 stop blocks, the follower boards and the sills in a relatively movable relation, whereby when the tank is shifted in either direction through the follower boards, the stop blocks rearwardlyA of the direction of movement will be carried forwardly with the depending portion, causing a corresponding compression of both of'the springs.

3. A car structure including a tank; a supporting structure therefor upon which the tank may move longitudinally with respect tov the supporting structure; a connection taking part inholding the tank down and which is attached to the tank and is moved by the tank upon and longitudinally of the supporting structure; and means for preventing vertical movement between said connection and the tank supporting structure without preventing longitudinal movement of said 'tank and connection.

4. A car structure including a tank; a supporting structure therefor upon which the tank may move longitudinally with respect to the supporting structure; a connection taking part in holding the tank down and which is attached to the tank and caused to slide by the tank upon the supporting structure; and means for preventing vertical movement between said connection and the tank supporting structure without preventing said longitudinal movement of the tank land said connection.

5. A car structure including a tank; a supporting structure therefor upon which the tank may move longitudinally with rerea spect to the supporting structure; a connec- E tion taking part in holding the tank down .and which is attached to the tank and is caused to slide by the tank upon and longitudinally of the supporting structure; and

means for preventingvertical movement between said connection and the tank supporting structurev without preventing said longitudinal movement of the tank and connection.

6. In a tank car, spaced sills, a tank above I said sills, an anchor member depending from said tank between said sills, means connecting the tank and sills in slidable relation, spaced cushioning means adapted to contact with each end of said a'nchor member, and I means connectingl said spacedv cushions.

7. In a tank car, spaced sills, a tank above said sills, an anchor member depending from said tank between said sills, means connectingl the tank and sills in slidable relaberand slots in Isaid sillsand held in substantially fixed relation With said anchor member, and cushioning `means connected.

With said sills in alinement With said anchoring member longitudinall of said sills.

9. In-a tank car, space sills, a tank movable relative to said sills, a tank anchor ldepending loeloW the top of said sills, cush.
